An elastomeric suspension system for wheeled vehicles includes an equalizing beam pivotably mounted about its center to a trunnion tube which is rigidly mounted to the frame of the vehicle. The trunnion tube is press fitted into an aperture in a trunnion rubber bushing which, in turn, is press fitted into an aperture in the equalizing beam. Near each end of the equalizing beam is an axle mounted transversely to the beam. Each axle has mounted thereon one end of a cylindrical elastomeric spring which is connected at its other end to the equalizing beam. A rebound shaft is slidably connected at one end to each axle and at the other end to each end of the equalizing beam to prevent excessive rebound of the equalizing beam with respect to the axles. Each axle is pivotably connected to a central portion of the equalizing beam through radius rods. The elastomeric rubber spring isolates a substantial amount of vibrations of the axle, particularly vertical vibration, from the equalizing beam. Each radius rod acts as a guide for the vertical movement of a respective axle. The trunnion rubber bushing further isolates any vibration of the equalizing beam from the trunnion tube. |
